Flux toasts now have an inverted treatment: dark in light mode, light in dark mode. Add invert to the toast component in your layout:

<flux:toast invert />

That sets the appearance for every toast. Your existing Flux::toast() calls stay the same.

The contrasting surface gives the message a little more separation from the page. Headings and body text switch colors with it, along with links, action buttons, and the close button's hover state.

You can still distinguish a successful save from a warning. invert controls the appearance, leaving variant available for the message:

Flux::toast(    'Changes saved.',    variant: 'success',);
